Digital Information

What is the difference between a bit and a byte?

• There is no difference.

• One is computer, another is when you eat.

• A bit is one place value either a 0 or a 1, and a byte is 8 bits.

• 8 bytes equals a bit.

How is a bit represented on a computing device?

• As a 0 or a 1. 0 is off. 1 is on.

• As an image you create.

• Depends on how many letters are used.

• As a single byte.

Do you understand how computers represent complex information?

• They represent them as binary, a complex base-2 numbering system using 0's and 1's.

• They represent them in images, which are pulled apart and put back together.

• Computers do not represent any complex information.

• Multi-level base-10 using ASCII.

What are the similarities and differences in how binary, ASCII, and RGB is represented?

• ASCII uses binary to represent text characters, while RGB uses binary to represent colors through combinations of red, green, and blue values.

• ASCII and RGB are both based on base-10 representation.

• ASCII represents colors, while RGB represents text characters using binary.

• Both ASCII and RGB use binary to represent numerical values only.

What is the difference between digital and analog?

• Digital representation uses discrete values, while analog representation uses continuous signals.

• Digital representation can only represent audio, while analog can represent video.

• Analog representation is more accurate than digital representation.

• Digital representation is slower than analog representation.

What are overflow errors? What are round-off errors?

• Overflow errors happen when calculations exceed data type limits -or memory allowed-, while round-off errors occur when numbers are approximated.

• Overflow errors are caused by incorrect data types, while round-off errors are due to data loss.

• Overflow errors occur during data transmission, while round-off errors happen during data storage.

• Overflow errors are related to memory allocation, while round-off errors are related to network latency.

What is an example of a base-2 numbering system?

• Decimals.

• Fractions.

• Binary.

• Whole numbers.

What is an example of base-10 numbering system?

• 0000000010.

• 0123456789.

• 1111111111.

• 0000000000.

Describe the main characteristic that differentiates lossy compression from lossless compression.

• Lossless is better.

• Lossy is better.

• They both have their uses. Lossy however removes data permanently while Lossless will retain the original data.

• Lossy compression is a unique algorithm used for pictures and texts while Lossless crunches video and audio only.

What is intellectual property?

• Special laws protecting copyrights, patents, and trademarks.

• Prohibits the downloads of software, games, music, and movies that are created and/or owned by others.

• Protects ideas, concepts, and symbolic creations.

• All the above.
